Agitation Leaching Theory And Practice Biology Essay

Gold recovery from sulphide ore is poor because the cyanide preferentially leaches the sulphide minerals rather than the gold, and cyanide is consumed by the formation of thiocyanate. These ores are subject to a concentration processes such as flotation, followed by a secondary process to oxidize the sulphides, thereby limiting their interaction with the cyanide during the gold leach.

Cyanide fact Sheet Intelligence and Technology

The cyanide process of gold recovery enabled a higher percentage of gold and silver to be extracted from hard rock, making many operations viable that would otherwise have had to close. Cyanide is used in the electroplating industries, the tanning industry and in specialized laboratories. A complex cyanide, Prussian blue, is used for dyeing jeans.
